Evaluate effectiveness for three products at increased time and concentrations
The three products that showed improvement in the previous trial were diluted to 10% using DI water in 600 ml beakers. Each solution was heated to 110 F and degassed for 5 minutes in a Crest 40 kHz Ultrasonic unit.
Nine preweighed coupons were coated with the beeswax and weighed again. Three coupons were cleaned for 10 minutes followed by a tap water rinse at 120 F for 15 seconds and a heat gun drying at 300 F for 1 minute.
Final weights were recorded and efficiencies were calculated.
Increasing the cleaning time and concentrations increased the efficiency for the three products tested. Inproclean and Texolite removed over 95% of the wax in the 10 minutes. The Polyspray product increased from 73% to 80%.

Success Rating:A follow up test, usually based on company input.
The effective cleaners will be tested on wax removal from glass coupons using ultrasonic energy. Cleaners to evaluated are: Inproclean 3800, Texolite 1734 XL, Bio T 200 A, Histo Clear and Opti Clear.
